قُلْ أَنفِقُوا۟ طَوْعًا أَوْ كَرْهًا لَّن يُتَقَبَّلَ مِنكُمْ ۖ إِنَّكُمْ كُنتُمْ قَوْمًا فَـٰسِقِينَ
“Say, [O Prophet,] "[Whether you] donate willingly or unwillingly, it will never be accepted from you, for you have been a rebellious people."”
Part of the well-established hypocrites-who-stayed-behind-from-Tabuk passage of Surat al-Tawbah.
